But you generally don't have everything you need. As I've mentioned most cameras' USB webcam output (if at all present) is quite bad, even via the official programs or gphoto. The 'correct' way to access video output is through their, well, video-out port (usually HDMI), which almost necessitates a capture card or monitor.

No, they are not. The USB port is (usually) USB 2.0 and the video output, even though the application might claim 1080p 30 FPS, is a 'digital upscale'[1] from XGA or 720p. That in my view is decidedly not 'high quality'. My monitor has eight times that resolution and more than four times the framerate, totalling more than a 32× increase in bandwidth, and it is from 2021.
If users want high-quality video out from their pro cameras, use a capture card or monitor. That's how it's always been. As another commenter said, this article is rage-bait because the OP has purposely chosen a decidedly poorly-supported way to use their camera's functionality instead of the industry standard.

Did you bother to look up literally any part of your comment?
The Canon G5 X II has USB 3.1 over a USB-C port. All of what you said does not in any way shape or form apply to the topic at hand.
Without loss of generality, the USB spec doesn't matter. The overwhelming majority of dedicated cameras are not set up to supply high-quality video output through their USB ports. Mass storage definitely and MTP, maybe, but video out? No, and even if you get it, it is badly nerfed. The industry standard is HDMI capture, or writing to disks in slots—whether SD, CF Express, or even M.2 NVMe.
This entire comment section is a massive storm in a teacup by photography and AV amateurs who don't know the ins and outs of AV work flows and assume that stuff should just work the way they want it to.
Evidently these cameras are capable of exporting high quality video via USB, if you pay 5 bucks a month. This doesn't sound like a hardware problem. It also has a control channel, unlike HDMI.
